OSCILLATING PRINTING-PRESS.

SPECIFICATION forming part Of Letters Patent No. 229,675, dated July 6, 1880.

Application filed March 2, 1880. (ModeL) To all whom it may concern Belt known that I, EDWIN M. CORYELL, a resident of Brooklyn, in the county of Kings, in the State of New York, have invented a new, useful, and important Improvement in Printing-Presses, described in this specification.

My invention consists,principally, of an arm having a slot to move in contact with a fixed bearing, and operating mechanism to give the requisite period of motion and rest to the platen and afl'ord ample time to feed the press and secure a good impression.

Figure 1 is a perspective view of one form of press involving my invention. Fig. 2is alongitudinal vertical middle section, and Fig. 3 a rear vertical view of the same.

In this form of press, A A are side frames, supported by cross-bars a. b c d. B is a driving-shaft, to which motion may be imparted by crank, treadle, pulley, or gear, to suit the power to be employed. 0 is a pinion on the driving-shaft. D is a gear-wheel into which the pinion meshes. G is a pitman connecting the crank and the arms H I of the togglejoint at h.

The arm H is supported on its outer end on cross-bar c. The arm I has a slot, m, through which passes the cross-bar 01, having a roller, n, to fit the slot.

0 is a cross-bar passing through the slotted arm at k, and connecting the arms q r to the platen-support S, which is supported on crossbar t, and to which the platen Nis adjustably connected. V is a bed secured to the side frames.

to feed the press and to secure a good im-.

pression.

Changes may be made in the construction and operation of the press within the scope of my invention.

I claim as my invention- 1. The combination of platen N, bed V, arms q r, bar 0, toggle-arms H I, the latter having guide m, bar d, having roller n, pitman G, crank-shaft B, gear-wheel D, pinion 0, drivingshaft B, and frame A, substantially as described.

2. The combination of platen N, arms (1 1*, bar 0, toggle-arms H I, the latter having guide m, oar 11, having roller n, and operating mechanism, substantially as described.

3. The combination of a platen, a togglejoint one arm of which has a guide, substantially as described, a bearing for the guide, and intermediate and operating mechanism, substantially as described.

In testimony whereof I hereunto subscribe my signature and affix my seal, in the presence of two attesting witnesses, on the 23d day of February, 1880.
